The purpose of this study was to investigate the effects of childhood obesity on school adjustment and whether the effects were mediated by withdrawal. Using the 2015 Korea Welfare Panel Study data, this study conducted a hierarchical regression analysis to examine the mediating effects of withdrawal on the relationship between childhood obesity and school adjustment. In addition, a Sobel test was used to consider the statistical significance of the mediating effects. Findings were as follows: First, childhood obesity had a negative influence on school adjustment. Second, childhood obesity affected withdrawal positively. Third. withdrawal had a negative impact on school adjustment.

First, it was analyzed that the social withdrawal had a statistically significant negative(-) effect on the self-esteem. Second, it was analyzed that the social withdrawal had a statistically significant negative(-) effect on the life satisfaction. Third, it was verified that self-development Youth Activities had a moderating effect in the relationship between social withdrawal and self-esteem.

This study examined how social withdrawal as an individual factor and discrimination as a contextual factor contributed to depression caused by peer victimization among middle school students. Self-reported data of 1,611 students from 86 classrooms in 7 middle schools was analyzed, using multilevel path analysis. The results indicate that peer victimization had a significant partial mediating effect on the relation between social withdrawal and depression at the individual level. Social withdrawal had a direct positive effect on depression as well as an indirect positive effect on depression via high levels of peer victimization. Discrimination also positively predicted peer victimization at the classroom level. Moreover, classroom-level discrimination moderated the individual-level relations between social withdrawal and peer victimization. The relation between social withdrawal and peer victimization was much stronger as the levels of discrimination in the classroom were higher. These findings shed light on the importance of considering both individual and contextual factors when intervening to prevent peer victimization.

To accomplish the purpose, 1,158 subjects were selected from the 8th(2018) data of the Multicultural Adolescents Panel Study(MAPS), and the data collected were analyzed by using Process Macro Model and Bootstrapping analysis. The major findings are as follows. First, positive bicultural acceptance attitude of multicultural adolescents was shown to decrease their social withdrawal and depression. Second, social withdrawal of multicultural adolescents affected increase of their depression. Third, the effect of bicultural acceptance on depression of multicultural adolescents was partly mediated by their social withdrawal.

This paper estimates the effect of minimum wages on new hiring of low wage workers from a time-series. The results indicate that minimum wages tend to reduce the new hiring of low wage workers, in particular, among women, less educated and older population. The strongly negative effect on new hiring suggests that the burden of reduced labor demand arising from higher minimum wages tend to fall mostly upon the unprotected low-wage job searchers due to the short-term rigidity of employment adjustment among the existing workers.

정부의 환경규제로 인하여 한국 제조업의 기업들이 공해방지시설을 의무적으로 설치해야할 경우, 이는 생산비증가와 신규투자의 위축 및 생산요소간 조합비율에 영향을 미침으로써 직 간접적으로 생산성의 감소를 초래한다. 본 연구에서는 인과추정법(因果推定法)으로 측정한 그레이 (Gray, 1987)의 모형을 통하여 환경규제가 한국 제조업의 생산성에 미치는 효과를 측정하였다. 측정결과, 규제로 인하여 연평균 0.58퍼센트 포인트만큼의 생산성감소효과가 있었다. 여기에는 생산성증가율 계산상의 '측정효과(測定效果)'만 존재하고 생산과정의 제약, 신규투자의 위축, 다른 생산요소의 생산성감소로 인하여 총생산성이 감소되는 '실질효과(實質效果)'는 발생하지 않았다.

For this study, we used data from the 13th wave the Korea Welfare Panel Study(KOWEPS). The analysis was conducted on 391 middle school students. Structural equation modeling by using AMOS was used for this study. As results of the study, the biggest effect on the suicidal ideation was the total effect of school violence, and the direct effect was also significant. In other words, school violence is a partial mediating effect through depression and withdrawn on suicidal ideation. Parental violence was more indirect effect than direct effect through depression on suicidal ideation. In other words, parental violence is a complete mediating effect through depression on suicidal ideation. Academic stress was more indirect effect than direct effect through depression and withdrawn on suicidal ideation. In other words, academic stress is a complete mediating effect through depression on suicidal ideation. Withdrawn was not direct affect, but had an indirect effect through depression on suicidal ideation. Therefore, in order to prevent suicide of middle school students, there is a need for prevention of school violence, parental violence and academic stress, which are causes of depression.

Data was obtained from the Korean Children and Youth Panel Survey, and study subjects included 2,409 first grade middle school students. Data was analyzed using the SPSS 25 program, and frequency analysis, descriptive statistical analysis, correlation analysis and hierarchical regression analysis were conducted. The results of the study are as follows: First, psychological withdrawal in the social relationship had a significant negative effect on the life satisfaction of adolescents. Second, peer attachment did not have a moderating effect on the relationship between social withdrawal and life satisfaction of adolescents. Third, positive parenting attitude had a moderating effect on the relationship between social withdrawal and life satisfaction of adolescents. The high-positive parenting attitude group showed less decline in life satisfaction even if social withdrawal was high compared to the low-positive parenting attitude group. Based on these results, we provide effective direction of intervention to elevate the life satisfaction of adolescents experiencing social withdrawal.
